IMPROVEMENT IN SASH-HOI'JDIEIRS` The Schedule referred to in theseLetters Patent and making part of the me.

To all whomflt may concern:

p Beit known that I, DANIEL M. DonnHoo, of Beaver Court-House, in the county of Beaver, and in the State of Pennsylvania, have invented certain new and useful improvements in Sash-Fasteners; and do .hereby decla-re that the following is a full, clear, and exact descript-ion thereof, reference being had to the accompanying drawings, and the letters of reference marked thereon.

In the annexed drawings, making a part of this ger, the lower extremity of the catch D is withdrawn or unhooked, and the window may then be raised as high as desired, and there held, by means of said catch hooking into one of the teeth of the ratchet-bar B.

Itwill be readily seen that the above-described device is a cheap, effective, and convenient fastening for window-sash.-

I am aware that the combination of a cam and a vertical rack-bar, for supporting a window-sash, is not new. My invention relates to `the peculiar construction of the catch operating upon the rack-bar, which is connected upon the window-frame, so that the jar of the sash, by wind or otherwise, will not allow the catch to become disengaged. I use no spring or deconstructed in any known 0r usual manner, and B represents a ratchetebar attached to the inside of said frame A, and extending from near the foot, or bottom of said frame, as high as may be desired.

The frame A is provided with a suitable recess, or notch at the lower extremity of the ratchet-bar B, as shown in the drawings.

Grepresents the side ofa window-sash made to fit in the frame A, and has pivotcd in a suitable recess therefor, a catch, D.

The catch D is made so that its outer end is the heaviest, and in the form as shown in the drawings, and is provided with a pin, g, which works in a slot, x, of the plate F, which is made of suicient size, and for the purpose of covering and holding the` catch D in its place.

When the sash is down in place, the catch lD drops vice to keep the catch even in position. My catch operates by gravity alone. by a spring soon become loose by wear, and weaken,

vice inoperative.I

What I claim, is The segmental catch D, provided with a. downwardprojecting point at its outer end, and pivoted in the window-sash, under the slotted plate F, incombination with the stationary rack-bar upon the frame B, all as herein shown and described. v

In testimony that I- claim the foregoing, I have hereunto set myhand, this 10th day of January, 1868, l v DANIELIL DONEHOO.
